I need to know if the red lens has "H-D 125" embossed on the nose of the red lens (it has the same part # as the 125/165 lens) and also if the hood has 3 rivets or is spotwelded.

I have a couple of NOS hoods that are riveted. I also have an original 1951 125 that has the riveted hood. What I am trying to determine is when the hood went from riveted to spotwelded (or visa versa)
The vast majority of the hoods I have seen are spotwelded
Any ideas?
